<longdescription lang="en">
Isabelle is a generic proof assistant. It allows mathematical
formulas to be expressed in a formal language and provides tools
for proving those formulas in a logical calculus. The main
application is the formalization of mathematical proofs and in
particular formal verification, which includes proving the
correctness of computer hardware or software and proving
properties of computer languages and protocols.
